LIGHTER FOR GAS-STOVES.

Specification of Letters Patent.

Patented June 15, 1915.

Application filed December 21, 1914. Serial No. 878,367.

therein to the accompanying drawing.

My invention relates to improvements in lighters for gas stoves.

The object of my invention is to provide a lighter located between thefour burners of a stove and so arranged and constructed that the flamewill travel across to the several burners and ignite the same, and alsoproviding a pilot light arranged centrally within the lighter and fedwith gas by a separate pipe leading through the supply pipe of theburner whereby the lighter will instantaneously ignite therefrom.

Another object of my invention is to provide a lighter of this characterwhich will produce two flashes to ignite the burners by a singleoperation of the'valve and thus'insure of the ignition of the burnersduring one or the other of the flashes.

A further object of my invention is to provide a simple, cheap andeffective lighter of this character adapted to be readily applied to theordinary gas stove and having certain details of structure and operationhereinafter more fully set forth.

In the accompanying drawing, Figure 1 is a perspective view of myimproved lighter.

Fig. 2 is a side elevation showing the burner and pilot light insection. Fig. 3 is a top plan view of Fig. 1 showing the controllinvalve in section, and also showing the bel surrounding the burner. Fig.4 is a dlagrammatical view of a stove showing my lighter appliedthereto.

Referring now to the drawings, 1 represents the casing of my improvedvalve wh ch is provided with a tapering central opening 2 therethroughin which is arranged a correspondingly shaped turning plug 3 having atransverse passage 4 therethrough. The casing 1, is provided with anopening communicating with its rear end and having its 7 forward endcommunicating with the central opening 2. Communicatin with the opening2 at the forward end of the casing is a passage 6 which has its outer.end in more fully communication with the enlarged internal threadedrecess 7. The plug 3 above the casing is provided with a housing 8having a sprmgtherem adapted to hold the valve in 1ts normal positionshown in Fig. 3 of the drawing. The said housing 8 is provided with ahandle 9 by means of which the plug is oscillated. The lower endof theplug extends below the housing and is screw-threaded and has screwedthereon a nut 10. Between the nut 10 and the housing 1 and surroundingthe extension of the turning plug is a coil spring 11 which normallyholds the turning plug in a downward position to form a tight joint withthe housing to prevent the leakage of gas therefrom.

Screwed within the internally screwthreaded recess 7 of the housing is apipe 12 which leads outwardly and has screwed thereon a casting 13 whichwill be later described. The housing 1 is provided wit a bypass 14extending around the turning plug 3 and communicating with the pipe 15arranged within the pipe 12 as clearly shown in Figs. 2 and 3. I

The casting 13 is screw-threaded on the pipe 12 and has a. passage 16leading diagonally upward to the enlarged recess 17 arranged in theupperend of the casting.

Bemovably secured in the recess 17 1s the burner or lighter proper 18which is provided at its upper end with the horizontally arrangedopenings 19 through which the gas passes and flashes outwardly as willbe hereinafter more fully described.

The portion 19' of the casting 13 is adapted to support the bell 20having the usual opening through which the I flame flashes through theopenings 19 as fully described in a co-pending application executed oneven date," 1915.

The pipe 15 extends inwardly within the casing as indicated at 21 andcommunicates with a vertically disposed passage 22 communicating withthe pipe 23 which extends upwardly through the burner 18 and has itsSerial No. 658, filed January 5,

upper end 24 open and which forms the pilot light which is continuouslyburning. order to control the amount of gas passing to the pilot burner,I provide the casting with a nipple 25 into which is screwed a screwvalve 26 having the tapered inner end 27 extending Within the end 21 ofthe pipe 15 and whereby the gas is controlled to the passage 22 forincreasing or decreasmg the pilot light.

In Fig. 4:, the bell 20, as shown, is located 5 centrally between theburners 28, 29, 30'and 31 and there are arranged four openings 19 in theburner 18 to shoot the flame out through the bell in the direction ofthe arrow shown in Fig. 4 to ignite the severa burners. From theforegoing description it Wlll be seen that when the turning plug isturned with the passage 4 in the direction shown in dotted lines Fig. 3,a certain amount of gas has passed through the passage 4 to the pipe 12and out through the passage 16, to the Y burner 18' and flashedoutwardly through the openings 19 and ignited by the flame at the pilotburner. .This pilot burner, as hereto- 20 fore described, iscontinuously receiving gas through the bypass 14 and the pipe 15 and istherefore continuously burning. When the turning plug is released, thespring within the drum 8 orces the plug 3.back to the position shown inFig. 3 shownin full lines,

and a second supply of gas passes through the passage 4 as it registerswith the passage 5 and thus supplies a second supply of gas to the pipe12- to cause a flash from the openj comprising a vertlcally disposedburner havings 19 clearly shown in Fig. 2 of the drawing.
